So I was out at dads yesterday and loaded up some 357 max with 180 great xtps. Shooting 24.5 grs lil gun for a fuzz over 2000 fps. Seemed to shoot real good at least left and right at 50. Group was a little under an inch wide but was stringing about 4 inches vertically. At the moment I am blaming myself I didn't have a good rest by any means and believe the lack of a good rest and possible small changes in grip are what caused the stringing especially since my left to right was so good. Just wondering if anyone else has a similar experience my standard deviation was 55 fps which should not be enough to cause that much difference at 50

I am interested in what other folks have to say here, but I often encounter stringing and think about it the same way you do. If I focus on consistent grip and consistent down pressure on the forend of the gun then it seems to get better.

CONSISTENT GRIP! ,no down pressure,let the bags hold it,same placement on the bags just in front of the trigger guard,straight to the rear trigger squeeze,follow thru.

I agree with junebug, just let it rest, no intentional down pressure. A 2000 fps load with a 180 XTP is going to come up off the bags. I am pretty sure the vertical stringing is grip & rest related.

AND a consistent crimp on a consistent case length!

That's what I thought that my form was causing an issue. The thing is super jumpy it's a 10 inch octagon with that load you really got to hang on or you risk the whole gun ending up on the ground behind you..... I didn't even have bags I was shooting off a lead sled turned sideways with my sweater laying on it..... I would agree with the crimp if my deviation was higher or the range was farther but my deviation was acceptable to me and I can't crimp with the bullet set out that far my goal is 2.220 and I'm just barely off the lands.

WOW a 10 Inch Octagon. A buddy of mine had one in 30-30. It was the hardest recoiling Contender I ever fired. Unpleasant was an under statement.
BushytailBasher you would enjoy shooting a 357 Maximum a lot more in a 13-15 inch Heavy Barrel version. That thing has to be brutal.

Bullets not seated the same depth can cause vertical stringing and the other is the rest that (bag) is soft. Bench rest shooters are your example here,, Use a Hard or fully packed bag on the front rest. Shifting sand bags will cause you problems.
For checking accuracy it is best to have the butt on a rest as well.

FWIW With my grip hand, it never leaves the pistol when shooting for accuracy test. Revolvers are easier than the Contender but still possible.

Have you tried backing down off that charge? Don't understand the reason for that high of charge with Lil Gun and would ask consideration of using 4227 for a real accurate load. Even if you dropped down to 1400 FPS, that would get the job done for most things.

That seems like a really hot load. It's impressive, but would be interesting in that barrel! I believe my load was doing 1800+ with that bullet in a 10" bull barrel and wasn't too bad. It seemed like an effective load on the whitetail I took with it.

Well where I'm at we are limited to straight wall cartridges in pistol or rifle so I'm trying to bring all the range I can out of it I believe I could load hotter but don't see any reason.... A few spots I like to hunt have shots all the way out to 200 and if like to have plenty of smack at that range and I just can't load my 45/70 stout enough for that trajectory.... The little booger is a handful have toear gloves to protect my fingers from the trigger guard and shooting it a lot is rough on the wrist as far as actual recoil it's not bad it's just snappy. Up there it should have said c.o.a.l. is 2.220 I'm certainly not hunting for more velocity at this point. And I didn't have any 4227 since last place I looked it was 10 dollars more a can than pistol powders. I've still got a little space in the case and I think 4227 would fill it out a little better. Last year I was shooting the 200 ftx at 1800 and it shot great at 50 couldn't even tell you fired more than one bullet but it was to heavy and by 100 yards accuracy fell apart since my barrel is a slow twist. I was shooting off Cornhole bags last year and that seemed to work real well but squirrels ate them.... I was really thinking my issue was grip and rest the shots that didn't string we're in a spot about 3/4 of an inch though which is where most of the shots went and I'm sure it's be smaller with a better rest.... Gun season starts the last week of this month here so we will see how that bullet works at that speed real soon. Though I'm going to try to get a little time behind the 450 Bushmaster upper dad ordered for the ars. Good shooting guys
